2. Figure 1
Chest radiograph reveals a normal-sized heart with ill-defined diffuse increased lung density with resultant poorly defined pulmonary vasculature. Neither pleural effusion nor dilatation of the pulmonary arteries is present.

3. Figure 2
High-resolution CT scan of the chest shows bilateral diffuse ground-glass opacities sparing the right mediobasal lower segment. There is considerable noise throughout the image, creating an impression of nodularity. The interlobular septae are conspicuous by their absence. There is no pleural effusion. The heart size and the diameter of the central pulmonary artery are normal.

4. Figure 3
A, Lung histology shows multiple areas with thickening of the alveolar septae due to abnormal proliferating capillaries, hematoxylin-eosin stained. The architecture of the small pulmonary arteries, veins, and bronchioles is normal; there are no signs of interstitial fibrosis (original magnification ×65). B, Capillary proliferation was confirmed by immunohistological staining with anti-CD31 antibodies (original magnification ×65).
